I could start by handing the former New York Met a copy of St. Louis' 101 Best Restaurants (as compiled by St. Louis Magazine last October), but it’s better to hone that list. Since I’m not privy to Piazza’s culinary tastes, I’ll keep the recommendations fairly general. (And to further simplify, I’ll stay clear of all chain restaurants, with which I’ll assume the worldly Piazza is already familiar.)
